10 Claims. ,1

The invention relates to the supporting and guiding of brake beams fromadjacentparts ofa railway vehicle, such as a truck side frame, andconsists more particularly in a beam structure having a relativelymovable element which may be projected into position to oppose the:supporting part or retracted to a position to facilitate the assemblyand disassembly of thebeam and other parts'of the vehicle structure.

The main object of the invention is to sime plify the supporting andguiding of the beam from the vehicle part and to facilitate the ap--'plication and removal of the beam and to a void substantialmodification or adjacent vehicle structure or the attachment of movingparts thereto, as shown in Letters Patent Nos. 2,254,513 and 2,254,514issuedto the present inventor September 2, 1941. The present applicationis a division of an earlier application Serial No. 474,- 527, filedFebruary 3, '1-943,'now abandoned'which applicant relies upon for anproper purposes.

In the accompanying drawings illustrating the invention- ,lFigure 1 isin part a side elevation of a railwayfou'r-wheel truck with "brake beamsupported upon the truck frame, a "portion of the frame beingIbroken'away and sectioned tomore :cl'e'arly illustratethe construction.

'Figure 21s a 'top'view of one end of the brake beam indicated in FigureI andshowingportions of the adjacent wheelandtruck frame, 'thesame beingdrawn to an enlarged scale.

Figure 3 is a detail vertical section taken on the line 33 of Figure 1.

Figure 4 is a detail section and elevaticn'taken onthe line 4-4 ofFigure 3.

Figure 5 corresponds generally to Figure 13 but. illustrates anotherform of the invention.

Figure 6 is a detail section and elevation taken onjthe line 6-4;o'f'Figu're '5.

Figure 7 is a top plan View of "the structure shown in Figures '5 andfi.

The illustrative "truck shown .inrliiguresll-sa illeludes wheels I'mounted on the usualaxles (not shown) provided with-journal boxes (notshown) which/support the truck side ira-mes, each of which comprises atop chordz, a bottomchordss andcolumns 4 (forming a window for *thebolster 5 supported on springs 16 seated on theirame lower chord 3. Thebrakes are appliedto the portions, of the wheelsrims; oppositertoathexholster and each brake gear includes. awtrusstype brake beamhaving acompression memberstgwaa tension member --8.::-a.nd a. brake,head 19: including :a bods ,2 portion having a pocket-forming member Itier receiving the end of compression member lt-he brake head beingseated on the compression member and held to 'itsseat by the nut H onthe end of the tension member '8 which passes through the pocket endwall Illa.

ill of the above-described structure 'is well known in the art and'initself does not-consti tute the present invention, which relatesto thecarrying of the brake beam from the adjacent truck parts 3 each of whichis provided with vertically spaced flanges +2 and 3 extending towardsthe adjacent end of the brake beam "but terminating short'of the same.

"The "brake head is provided with transverse apertures l4 aboveandbelowthepociketformemher I and tension member '8, and a U-shapedbracket 23 has vertically spaced legs "24 and 2. slidably received in"the lower and upper @PBI'? tures respectively in the brake head.Preferably the brake head portion I'U includes a lateral flange 26",forming an ,extendedibearing ilor bracket upper leg "25.. Aibolt 21may bet-passed through flange 2B and br'acketleg Z'Bto hold the bracketimprojected position. vA supplementary holding means is provided by abolt 28 passed through lower leg of. the bracket and the lower flangeofhthe compressionmember. ,1

With this arrangement, bracket (23 when lpro jected, supports the end oftheiheam upon the lower flange .12 on the truck frame andrcoopen ateswith the upper flange l I13 fthe truck name to guide the beam in itsmovement tor-and from the wheels during the application and releasesofthe brakes. When the beam is assembled with thetruc'k, and again when itis to 'be removed from thetruchjbo'lts Z1 and 2,8 are ,removedand thebracket retracted to "the "broken linepo'sition indicated at 23c (Figure3.), thus providing fortheiifting and dropping oflthebeamz into or outofitsffunctionlngfposition, but it is unnecessaryto disassemble any ofthe beam parts ,for this purpose. I

Figures 5, '6, and 7 illustrate another form of the invention in whichthe compression member 30 and the'tension'me'nibe'r 31 of the elongatedstructure :of "the beam are formed bysplitting a rolled memberlongitudinally except Ettjits ends. The splitportions ofthe'elongat'edstructure are spreadto form the tension and compression members of thetruss. The end portions are flattened asindi'cated at "32400 be receivedwith in asuitable aperture in the *brake' 'head 333, *s'ecured to theflattened portion 32 by rivet -f3. Adfiacent "the flattemed hcadmounting end sec a V 3 a 2,460,780

and spreading forces applied to the beam and tending to cause failure atthis point. Transverse passageways 35 are formed in the head at thefront and rear of the head-mounting portion 32 of the elongated memberand above and below the level of portion 32. V

The U-shaped supporting bracket 36 has each of its legs bifurcated, asindicated at 31, with" each of its bifurcations received inpneofthe headpassageways 35. The bracket is notched it is received between flanges 4|and 40 on the the beam, and into a retracted position, in which itclears the truck part.

3. In a railway vehicle brake beam, elongated structure comprisingconverging truss tension and compression members, the ends of said"membersjbein'g reduced in height and merging in a fiattened sectiomabrake head having a transverse recess receiving said section, therebeing an upright reenforcing rib connecting the converging members andspaced inwardly of the beam from said section, a bracket elementextending thru the head and'over said flattened section longitudinallyof the beam to a proat 38 to receive a cotter 39 seated in a hole in andtoretractedl position in which its outer end jected position, in whichit may oppose a cooperating supporting element on a truck main part,

' is substantially flush with the vertical outer side truck side frameto support and guide the beam:

When cotter 39 is removed, the bracket may be retractedto the brokenline position indicated at 36a and the beammaybe moved vertically into.and out of assembledrelations with flanges 4| and 40. Rib 34 ispositioned inwardly of the inner end of bracket, legs 31 when thebracket is retracted.

. ,Each form of the invention embodies a simple,

effective structure for supporting one endof the beam directly from thetruck side frame or other adjacent main part of the vehicle in place ofthe usual swing hanger or in place of members integral with or fixedlyassembled with the main portions of the brake beam so thatthe beam canonly be removed by modifying the truck frameor other associated part forthis purpose. Ordinarily it will only be necessary to provide themovable bracket element atone end of'the beamf because dropping thatbeam end will enable theopposite end to be moved transversely of thevehicle to disengage opposing elements on the beam and frame formedrigid with the same. However, if conditions make such a method ofassembly and disaassembly impractical; then the movable bracket elementmay be provided atboth ends of the beam. 1
